When you open a drawing
in lightweight mode, notes and tables linked to custom properties show up-to-date values.
Previously, the values did not always update if the models changed after the drawing was
last saved. To achieve this new behavior, the models must be saved in SOLIDWORKS 2019 or
later.
In addition, the precision and units of custom properties in lightweight drawings and
assemblies are supported. Tables and notes reflect the Document Properties
Units settings of the active drawing or assembly without
having to resolve the components first. To achieve this new behavior, the models must be
created in SOLIDWORKS 2018 or later.
